Both sides -- Occupy L.A. and the LAPD -- are claiming the other backed off.

In a statement on its Facebook page, Occupy says it was all about the department's stance:

So what was different about last night and last month? There weren't 150 riot police present. Imagine that, riot police who come dress for a fight, not present and everything remains peaceful even with hundreds of more Occupiers and their allies around. Note: there are no documented cases of anyone ever being shot , tasered, or gassed with a piece of chalk.

LAPD Officer Rosario Herrera says it was all about Occupy's observance of the law. While July's clash started with chalking vandalism, a takeover of a busy downtown intersection and the throwing of rocks and bottles at cops, according to the department's take, none of that happened last night.

Herrera:

No one was vandalizing or blocking the streets, so everything was peaceful.

There were two arrests yesterday morning, one for a warrant and one for alleged battery. But what the LAPD considers vandalism was allowed to happen during an Occupy chalking event at nearby Pershing Square.

About 100 people showed up for the Chalkupy party about 7 p.m. and, two hours later, the crowd moved over the Art Walk along Spring Street, according to City News Service.
